[The morphogenesis of the microcirculatory bed in ontogeny and the pathology of its development in the early postnatal period in congenital heart defects].

Circulation system of the omentum majus is studied in human fetuses (42) and children up to 3 years of age (108 with a premature delivery and 73 delivered normally). Pathologic alterations in the microcirculatory system are shown to result, during an early postnatal period, from hypovolemia of the greater circulation and tissue ischemia.
